Okay, this has partly been resolved. Using strace I could see that horde tried to open /var/tmp/.horde/imp/compose and failed since the directory /var/tmp/.horde already existed but belonged to root with mode 400. The directory has been created 2008 and I suspect the ownership has been the same ever since, so I guess with the update to groupware webmail edition 5.1.0 the used path changed, since I didn't see these problems before. Adjusting the rights on the directory solved the issue.

In the strace I can see Vfs/Exception.php and Horde/Exception/Wrapped.php being opened but I don't see any error message in the log. This is reproducible, just make the .horde/imp/compose path inaccessible to the webserver and sending attachments will fail without error message. Should I open a bug for this ?

How is the decision made which path will be used for .horde/imp/compose ? On one server this is done in /tmp, on the other in /var/tmp although both have the same settings.
